IMPROVEMENT VIN ODORLESS-AIR `CL`OSETS` Specification forming part of Letters Patent No. 186,966, dated January 16, 1877; application filed December 8, 1876.

To all whom it may concern Be it known that I, GEO. R. MOORE, ofthe city and county of Philadelphia and State of for alvine discharges, by` which the escape ofV odors into any apartment where the said vessels may be used shall be entirely prevented, as well in closing the same as in other parts of their use. i

Figure l is a vertical transverse section of the entire closet, with vessel in place for use, and showing, also, in dotted lines, the close cover in place, as for the removal of the vessel for emptying. Fig. 2 is a-portion of the same view, introduced to show a frictionless disk immediately beneath the vessel, which is not shown in Fig. 1. i y

A-is the internal conducting pipe or throat, leading from the seat a down any desired distance, as a guide to the vessel, a protection to the air-pipe D, and an inside wall to the annul lar air-due C between it and the outside conducting-pipe Bg The arrows show in what direction the air must come into the closet to i reach the lue C and pipe I). When the vessel is in use there is no air-passage from the casing of the closet to the pipe. a is a lid to the closet, finished in the usual style of .privy-seats and hinged. b is a hinged cover to a. E is an elastic face or packing, attached to the conducting-pipe B at its lower end, so as to make an air-tight joint with the top outlying rim of the vessel F. f is a close The use of the disk G, with all its attachv ments, is to hold the vessel and to raise it at will, so as to give it an air-tight connection with the conducting-pipe B. Turning the disk to the right, the inclined planes are carried up upon the portion of the frame upon which they rest, and the vessel is thereby forced firmly upon the packing E at the terminus of the pipe B, and all communication of the atmosphere, except as it comes down through the seat and passes to thepipe, is cut oli'. In -this instance, two circular guides, e, at the top, and h at the bottom, are furnished to4 guide the vessel directly and conveniently to its place, so that no special observation is required. H is a side door to the casing. Obviouslyit is of no consequence about the casing, whether it is close or open work, as the contents of the vessel are never exposed to theair within it, and the pipe does not take any air from it as long as the vessel remains within it.

It is, of course, seen that I aim to preclude the possibility of foul air, even in the y case itself.

I claiml. The closet-frame and casing la: I, provided With the'adjustable disk G, upon inclined planes g, for raising and lowering the vessel F, substantially as and for the purpose herein set forth.

2. In combination, the adjustable disk G, the vessel F, or its equivalent, and conducting-pipe B, either with or without the elastic packing E, substantially as and for the purpose set forth.

3. In combination, the adjustable disk G and frictionless plate G', substantially as shown.

4. In combination, the vessel F and conducting-pipe B,provided with the guide 6, substantially as shown.

5. In combination, the throat A and the vessel F below it, provided with a cover-seat smaller than the smallest diameter ofthe said able vessel F, and the xed conducting-pipe throat A, whereby the coverf may be placed B,` provided with the air-pipe D, substantially upon its seat in the said vessel F by carrying as and for the purpose herein set forth.
